These creamy potatoes come together in minutes and are topped with a crunchy layer of cornflakes. A delicious creamy and cheesy flavor in every bite.
Stir in garlic powder, salt and black pepper to taste. Follow with ½ cup of cheddar cheese and stir until cheese is incorporated and melted. Remove from heat.
Let the casserole rest for about 10 minutes before serving (the sauce will thicken as it cools). Garnish with fresh parsley just before serving.
